CCW or CW Rotation? - Electric motors generators engineering - Eng-Tips If one looks at an electric motor the rotation can be CW or CCW depending upon which end of the motor one is viewing from Dumb question but I have forgotten how to determine CCW or CW so as to order a replacement
Phase Rotation-CW CCW - Electric power transmission . . . - Eng-Tips Although ABC rotation an CW and CCW are similar notions, they are different When conducting a mathematical vector analysis of a power systems, generators, and motors or other 3-phase system component an arbitrary starting point, for the analysis is selected
terminology for describing direction of rotation 1 - Eng-Tips I've normally seen rotation specified as CW or CCW from Driven End (DE) or Non-driven End (NDE) Sometimes Non-driven end is referred to as Opposite Drive End (ODE) But I'm left-handed, so YMMV
Phase rotation convention - Electric power transmission . . . - Eng-Tips Is it when the motor rotates clockwise - or is it when the vectors rotate CCW? Or both? The answer is that the sequence shall be A-B-C (L1-L2-L3 in Europe) and the only safe way to find out (at least in my opinion) is to connect an oscilloscope and read the timing between the phases
3 phase motor rotation 1 - Eng-Tips Given an 800hp G E Motor directly coupled to a fan why would the manufacturer stipulate the Motor as CW or CCW? I thought that three phase Motors could be reversed by simply switching stator conductors There is no anti-rotation device
